Scientific Method - You have too many diagrams which state the same thing.
The scientific method is the way scientists learn and study the world around them. The whole process can start from just a simple question, such as "why is the sky blue?" Scientists use the scientific method to then try and answer questions such as these. Little do we know, we actually use the scientific method all the time in our everyday life. One example of this is when you get a new remote control for your television, and you have to find out which button mutes it. So your question would be "What button on the remote mutes the t.v?" You would form your hypothesis and say "I think the button that has the volume and the x over it is the mute button." You would then test that hypothesis by pressing the button, and if you got it correct your hypothesis was right and the scientific method worked, and if you didn't get it correct you would form a new hypothesis, and try it again. - I like how you defined the sceintific method, and gave a good example of the hypothesis in a basic understanding. The real life situation is also one that any one with a tv can relate to so overall it is a good example.
There are many different steps in the scientific method. I kind of described some of them earlier, but here is a list of the real steps:
Define/Identify the Problem
Form a Hypothesis
Make Observations or Test Hypothesis and Perform Experiments
Organize and Analyze Data
Do Experiments and Observations Support Hypothesis?
If No, Perform New Experiments and Repeat Step 4
I beleive you can add more steps into this procedure. And could be explained in more depth.
Draw Conclusions
Communicate Result
There is even a diagram for the scientific method:

When looking at the different documents on the scientific method i noticed that most of them differ from each other. Some are very strict and say that it only relates to science and is not used in our everyday lives. -I couldnt find one website stating whether you couldnt use it in everyday life. While others say that it isn't just something used by scientists but by everybody in the world. For instance one document said that the scientific method is really just how we figure things out in life, but scientists just use it at more complicated levels. Scientists use the scientific method when dealing with more complicated questions or when they are trying to learn something new. All scientists use this no matter if you are a chemists or a zoologists it doesn't matter. However the way a chemists uses will probably differ from the way a zoologists uses it. A zoologists would most likely be observing and recording data on an animal to help with his hypothesis. While a chemists would actually be sitting down and preparing a whole experiment to prove his hypothesis. Not saying that a zoologists couldn't also do an experiment to help his hypothesis, but most of the time they don't.
Set up the data logger and probes How do you set up the probes?
Fill the 250 ml beaker with the water from the cooler.
Fill a 100ml beaker with cola. Do you start off with the cola or another liquid
Put the probe in the water from the cooler and record the data Record what data? The pH level? and do you record the data for water from cooler every time you repeat.
Then wipe the probe off and place it in the cola, and record.
Then put the probe in the water from the cooler and rinse it off
Repeat for all the liquids.
Make sure that your method is clear on what you are wanting your audience to do
Data Table:
Wheres uuuuh yur data table at.
Results:
Conclusion: Overall most of my predictions were pretty close to what the actual PH levels were. I made my predictions through using the knowledge that i already had of the liquids. For instance, when i had to predict for lime juice i already knew that limes were sour, and sour things are usually acidic. Overall i think that we did the experiment well, and i don't think that there were many errors that could've affected the data, except for maybe if someone didn't clean off the probe well enough, and they went straight from testing an acid to testing a base. In conclusion i believe Ryan and I conducted the experiment well, and that is shown through the results that we got. Theres no comparision with you and the other groups which is why we created the single graph of everyones data.- Owen McCleery

Research question: How does the amount of sunlight affect the CO2 levels in the biochamber?
Hypothesis: I think that the Co2 levels will be highest in the biochamber that is in the sunlight for the three minutes. I also think that the one in the shade will have a very low Co2 level.
Materials:
Data Logger
Laptop
Biochamber x3
CO2 probe
3 leaves on any type
Stopwatch x2
Method:
Take 3 leaves from anywhere but make sure they are the same leaf and that they have no holes or damage.
Set up the biochambers
Put one leaf in each biochamber
Keep one inside and measure the Co2 levels in the biochamber
Record the data
Then put one biochamber in the sunlight and one in the shade
Then start the stopwatch and wait for 3 minutes
Then take the probe and measure the Co2 levels in the biochamber
Record the data
Variables:
Independent- The amount of sunlight
Dependent- CO2 levels
Control group- the leaf that doesn’t go in the sunlight or shade
Control factors- the type of leaves, the biochamber
